Depends on which application you use
You could use an IF function to check if a value has been entered into a cell, and if it has to use the formula or else display nothing. So say you wanted to multiply the value in cell B3 by 10 if there was something in B3 or otherwise show a blank. Then in another cell that you wanted the result you would enter the following formula: =IF(ISBLANK(B3),"",B3*10) So in one part we check if B3 is blank. If it is, we have a pair of double quotes to put nothing into the cell. If it is not blank, we multiply B3 by 10. You could put whatever formula you need there. ISBLANK checks if the cell is blank. You can also use other similar functions, like ISNUMBER to check if there is a number or ISLOGICAL to check if there is a logical value, and some other functions. You can use whatever one of them is appropriate.

If the word Yes is in E8, the following formula will put Correct in the cell that the formula is in, or else leave it blank, which is done by have a two sets of double quotes with no gap between them after the final comma. =IF(E8="Yes","Correct","") You can exchange the Yes with whatever you are testing for and the Correct with whatever you want to put in the cell. Another thing you can do is use the IsBlank function to test if the cell is empty. If it is empty it will leave the cell with the formula blank or will put the word Correct in, no matter what is in the cell E8 if it is not blank. That may not be exactly what you want to do, but this would be the formula. =IF(IsBlank(E8),"","Correct") If you want to allow numbers to be in the cell, but no text you could use the IsText function: =IF(Not(IsText(E8)),"","Correct") Probably the first formula or a slight variation of it is what you are looking for.

Inter-sheet formulas in Google Docs are similar to those used in Microsoft Excel. Using this ability, you can post a value automatically in a cell on one tab that is calculated or posted in a cell on another tab. The format for the blank cell is ='[TabName]'![cell ID], so your blank cell on the inter-sheet destination cell might read ='SewerWater'!N17
You can use formulas. For sums you would be likely to make use of the SUM function. You can also use the AutoSum to automatically do the calculation. You can place the cursor under or beside the cells you want to sum, or select the cells and click the AutoSum and it will put the total into a blank cell.

Blank cells, which are cells with nothing in them at all, or cells with text in them because they are not numbers.
